DNA recovered from ancient caribou bones reveals a possible link between several small unique caribou herds and a massive volcanic eruption that blanketed much of the Alaskan Yukon territory in a thick layer of ash 1,000 years ago.

Some 135 years after its discovery, Mars' largest moon Phobos is seen in fantastic detail - and in 3D - in an image taken by ESA's Mars Express spacecraft as it passed just 100 km by. This view is much different to the faint object that astronomer Asaph Hall would have just been able to make out as he observ...

Is it OK to leave objects on the Moon? A British-led group wants to fund a Moon mission with public donations. Contributors to the Lunar Mission One project will have their photos, text and videos buried beneath the moon's surface. But is it legal - or acceptable - to drop stuff on the Moon and just leave...
